My rir 9 months old, have never laid. Is it what I am feeding them. I always have fresh water for them. Now it is freezing here, so I give them fresh, unfrozen water, every morning and afternoon. Food always there. I was giving layer crumbles or pellets, but just a few months ago, changed to a, so they say at the feed storew, homemade better laying food, it is like cake mix texture. Any ideas, why they are not laying. I check the coop 2 or 3 times a day, and try not toet them out until after they haVE TIME to lay, which they do not. I have checked for egg eating, and see no signs. Coop is enclosed, so I9 do not think pests are getting it. HELP
